Third Party Administrator (TPA)

An independent organization that provides administrative services including claims processing and underwriting for other entities, such as insurance companies or employers. Often insurance companies will contract as TPAs with other insurance companies or health plans. TPAs are not always insurance companies. TPAs are organizations with expertise and capability to administer all or a portion of the claims process. Self-insured employers will often contract with TPAs to handle their insurance functions. Insurance companies will sometimes outsource the claims, UR or membership functions to a TPA. Sometimes TPAs will only manage provider networks, only claims or only UR . Hospitals or provider organizations desiring to set up their own health plans will often outsource certain responsibilities to TPAs. TPAs are prominent players in the managed care industry.
